title USING EVOLUTIONARY ALGORITHMS TO AID DESIGNERS OF ARCHITECTURAL STRUCTURES
source Creative evolutionary systems, eds Bentley, Peter & Corne, David, Morgan Kaufmann, pp 315-336
summary This paper describes the application of an Intelligent Genetic Design Tool (IGDT) in the design of architectural, structural elements. As a computer design aid an IGDT is innovative in its intelligent interaction with the designer. By always submitting multiple solutions for review by the designer, it is less likely to cause design fixation than other optimization techniques, and allows the user greater range in exploring hard-to-code design criteria such as aesthetics. As an example, the design of a cantilever truss is briefly explored. Using the coded optimization criterion of weight, and the designer's non-coded criteria of visual aesthetics and performance, a series of possible designs are explored. The ability of an IGDT to intelligently respond to the designer's preferences in a way that promotes creative thinking on the part of the designer is demonstrated. A final truss design is selected based on the use of the tool. It is concluded that an IGDT offers a significantly different approach to computer aided structural design which has the potential to enhance the user's own creativity in determining a good solution.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London.

title A generative design system based on evolutionary and mathematical functions
source International Conference on Generative Art
summary Previous work by Professor John Frazer on Evolutionary Architecture provides a basis for the development of a system evolving architectural envelopes in a generic and abstract manner. Recent research by the authors has focused on the implementation of a virtual environment for the automatic generation and exploration of complex forms and architectural envelopes based on solid modelling techniques and the integration of evolutionary algorithms, enhanced computational and mathematical models. Abstract data types are introduced for genotypes in a genetic algorithm order to develop complex models using generative and evolutionary computing techniques. Multi-objective optimisation techniques are employed for defining the fitness function in the evaluation process.

title An Inquiry Into Computers in Design: When Cardboard Met Computer

summary This paper reflects on the experiences of teaching undergraduate design studios for past 4 years and presents a systematic investigation conducted in a classroom setting to further understand the role of computer in conceptual stages of design. A case study project inquiring the implications of using two different forms of media, namely cardboard and computer, for design development during conceptual stages is presented. Twelve novice designers were challenged to learn and use computers in a five-week design project. A conceptual framework for understanding the discovery and usefulness of computer in their design process was developed and tested. An analysis of the outcome indicated that computers played a positive role in student innovation, improving possibilities for discovery. It further revealed that the employing cardboard was useful in turning the abstract discoveries made by the computers into productive and useful design solutions. It also supported the notion that the novice designer’s use of photorealistic possibilities offered by computer visualization (rendering, animation) during conceptual stages of design had an effect of distraction rather than a design aid.

title Collaborative design of structures using intelligent agents
source Automation in Construction 11 (1) (2002) pp. 89-103
summary The construction industry has a long tradition of collaborative working between the members of a construction project team. At the design stage, this has traditionally been based on physical meetings between representatives of the principal design disciplines. To aid these meetings, the information and communications technologies that are currently available have been utilised. These have yielded some success but are hampered by the problems posed by the use of heterogeneous software tools and the lack of effective collaboration tools that are necessary to collapse the time and distance constraints, within which increasingly global design teams work. In particular, there are very few tools available to support distributed asynchronous collaboration. Distributed artificial intelligence, which is commonly implemented in the form of intelligent agents, offers considerable potential for the development of such tools. This paper examines some of the issues associated with the use of distributed artificial intelligence systems within the construction industry. It describes the potential for the use of agent technology in collaborative design and then goes on to present the key features of an agent-based system for the collaborative design of portal frame structures. An example is presented to demonstrate the working and benefits of the prototype system, which makes a significant contribution by allowing for peer to peer negotiation between the design agents.

title Making Sense of Presenting Design Ideas through Animated Form
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 560-563
doi https://doi.org/10.52842/conf.ecaade.2002.560
summary This paper describes both conventional and computational ways of expressing and exploring design concepts with the use of models. We explain the role and function of the model in the design process, and investigate the ways in which models become reflections and representations of architects’ design thinking. We compare and contrast the physical properties of conventional models with those of three-dimensional computer models, and the corresponding processes of model creation, model development, and model modification. The paper includes a brief overview of commonly used forms of computer representations often encountered in Computer Aided Design applications. Whatever the visual richness of computer models in virtual environments can be, we believe that, just as in the use of conventional two-dimensional architectural drawings, computational presentations of architectural design concepts have their own conventions of use. This paper addresses the need to more accurately understand these conventions of using computer models for the representation of architectural design concepts. Therefore, we will illustrate the more dynamic qualities of computer models, which have the potential to allow designers to escape from the restrictions and constraints of physical form. In particular, we demonstrate these qualities in the context of architectural presentations in the medium of computer animation. These new forms of expression of design thoughts and ideas go beyond mere model making, and move more towards scenemaking and storytelling. The latter represents new methods of expression within computational environments for architects and designers.

summary The cyberspace upon physical space forms a new spatial structure to increase the influence on the urban fabric and the concept of space in architecture. Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. How do digital cities directly connect to physical cities and become an imaginable city? Therefore, we argue that a new spatial analysis theory must be established for digital city, comparing with theories of disciplines, to find the explicitly spatial structures and relations in digital city upon physical city.

title Exploring syntax and semantics of spatial structure - A study on Traditional Taiwanese City form in Chi’i’ng Dynasty

doi https://doi.org/10.52842/conf.ecaade.2002.412
summary Abstract. In this paper, we want to figure out the relations of complex semantics and syntax on five traditional Taiwanese cities in Chi’i’ng Dynasty by using a language approach. The issues of traditional Taiwanese central city in Chi’ing Dynasty had been interpreting by historical, social, and cultural research but had lacked the explicit construction of spatial structure on semantics-syntax. Therefore, we use a data modeling on knowledge level to describe the relationship between syntax and semantics. Through the research of Chi’ing Dynasty‘s history, we find out the spatial relations of Taiwanese traditional city to establish the functional categories of spatial structures. Then the language of semantics components and the meaning’s attributes are coded as logical statements to map the elements of syntax on architectural form, political vocabularies, spatial layout, and spatial myth. We argue that using this approach several social and spatial structures of cities can be clearly defined and understood.

title Daylight and energy in the early phase of architectural design process: A design assistance method using designer’s intents
source Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 761-770
doi https://doi.org/10.52842/conf.caadria.2011.761
summary The integration of daylighting from the beginning of the design process can help designers to create buildings that respect their environment benefit from the solar gain thus giving an answer to illumination and energy needs (Bodart et al, 2002). This paper proposes a declarative assistance method/tool designed for the early design phase. This method assists the designer in integrating the daylight and its energetic impact from the beginning of the architectural design process by means of intents. The intents are related to the daylight, energy and spatial configuration aspects of the architectural project. The method translates the designer’s intents into potential solutions. They are the first formal representation of the architect’s intents that could be customized and altered during the next architectural design phases.

title Can a Genetic Algorithm Think Like a Composer?
source International Conference on Generative Art
summary There has now been a substantial body of work utilising Genetic Algorithms (GA) for the purpose of musical composition. A common point of discussion is how far GA’s can simulate not just the musical output of human composers, but also the process of composing itself. This paper begins by discussing the suitability of using a GA for composition, and goes on to describe a generative music system (by the author), that utilises a domain specific, knowledge rich GA. The system acts on a supplied 2-bar musical phrase (up to 4 parts), and evolves musical fragments towards a supplied target. The aim is to provide interim points on the evolutionary path, which represents a ‘new’ musical ideas audibly based on the supplied fragments. The paper concludes that the system is able to model at least part of the creative process of composition, and is effective at producing musically successful results. (Audio download sources of its output are included to support this conclusion). The system was used to generate music included in an interactive installation work, exhibited at Brighton Arts Festival 2002, and other applications under developed that use the algorithm are discussed.

summary The goal of our study was to identify how designers use and communicate early design ideas by using immersive three-dimensional VEs. We set-up a series of experiments including navigation- and perception-tasks; designing in immersive VE; transcription of design; remote communication between design partners and controlled observations. We explored initial intentions of 3D-immersive design schemes; textual descriptions and collaborations within immersive VE. This article describes the outcome of creation; interpretation and communication of architectural design; by using a three-dimensional (3D) maze together with text-based communication in a series of collaborative design experiments. We conducted the first successful attempt of a Joint Design Studio; which uses immersive VE as tool of design and communication between remote partners. We discuss frameworks and factors influencing how architectural students communicate their proposals in an immersive Virtual Environment Design Studio (VeDS); and how this new approach of design studio enables new forms of design expressions.

doi https://doi.org/10.52842/conf.acadia.2002.303
summary The design and construction of freeform glass roofing structures is generally accomplished through theuse of either planar triangular glass facets or curved (formed) glass panes. This paper describesongoing research on the constructability of such structures using planar quadrilateral glass facets for theJerusalem Museum of Tolerance project by Gehry Partners, in collaboration with Schlaich Bergermann& Partners, engineers. The challenge here lies not only in the development of a geometric strategy forgenerating quadrilateral planar facet solutions, but also in the fact that said solutions must closely matchthe designs created initially in physical model form by the architects.We describe a simple but robust geometric method for achieving the structure by incorporating thenecessary geometric principles into a computational parametric framework using the CATIA Version 5system. This generative system consists of a hierarchical set of geometric ‘control elements’, that drivethe design toward constructible configurations. Optimization techniques for approximating the generatedstructural shape to the original created by the designers are also described. The paper presents theunderlying geometric principles to the strategy and the resulting computational approach.

summary This paper presents some results of a quantitative process analysis of two types of courses in Computer Aided Architectural Design that were taught using database-driven online environments. It focuses on the performance of these online environments as information structures, designed to accommodate the presentation and the peer-to-peer exchange of design information for relatively large groups of between 60 and 150 participants. Using the database records to reconstruct the processes, three different quantitative analyses are described. Their results indicate that for these projects the webenvironments were successful in enhancing peer-to-peer learning and that they promoted a more objective assessment of the submitted works. The study also looks at the effect that the environments themselves had on the process. Finally it makes some conclusions about how such environments must be designed to handle the dynamic display of design data in a way that is transparent to the users.

summary In this paper we aimed at the development of a novel tool to facilitate the structured analysis of architectural construction principles, materials and production methods in digital design and fabrication practices. In order to assist the understanding and teaching of these subjects, we employed a taxonomy of spatial design construction (Vrouwe 2013). By using the taxonomy, we analysed and categorised 34 parametric structures published in the IJAC Journal (2002-2014). Informed by this study, we aligned the initial taxonomy using various framing strategies. As a result we developed a new framework for spatial design construction specifically customised for the design and fabrication of parametric structures which can potentially serve as a constructive tool to create a novel design learning environment and integrated teaching strategies.

summary This paper re-establishes the theoretical framework for participatory design evolved in the late sixties and early seventies as part of the movement towards a more explicit design methodology and attempts an explanation of why the concept failed to gain commitment from the architectural and urban design professionals. The issue of user participation in the processes of building and urban design is enjoying renewed attention following its relative neglect over the last 20 years due, in large measure, to significant advances in emerging information technologies, particularly multimedia, virtual reality and internettechnologies. This paper then gives an account of two significant and relevant developments in the evolution of the application of informationtechnologies with which the authors have been engaged. These are:a responsive and interactive interface to wholly immersive and realistic virtual reality representations of proposed buildings and urban neighbourhoods. an intuitive and platform-independent VR modelling environment allowing collaborative evolution of the scheme from withinthe virtual world. The efficacy of these IT developments is tested in the context of a design exercise in which three designers, from distributedlocations and using different computer platforms, collaboratively design an Information Centre from within the virtual world.

summary This paper presents the results from two experiments in working on descriptions of form in immersive virtual environments (IVE). Recently; Virtual Environments (VE) are increasingly used as environments for design and research. Using VE to visualize ideas from the initial steps of design; the architect is challenged to deal with perception of space; solid and void; without translations to and from a two dimensional media. From this new ability; we might expect new forms of design interaction and expression. The goal of our studies was to identify how designers use and communicate early design ideas by using immersive three-dimensional (3D) VEs and how they describe 3D volumes using different media. We set up a series of experiments including navigation- and perception-tasks; designing in IVE; transcription of design; remote communication between design partners and controlled observations. We explored initial intentions of 3D-immersive design schemes; textual descriptions and collaborations within IVE. This paper describes the outcome of creation; interpretation and communication of architectural design; by using an Immersive Joint Design Studio; as well as the description and translation of a 3D cubic structure. We discuss frameworks and factors influencing how architectural students communicate their proposals in an immersive Virtual Environment Design Studio (VeDS) and how this approach of design studio enables to understand volumes and spatial relationships.

doi https://doi.org/10.52842/conf.ecaade.2002.254
summary A new trend is emerging in architecture today: dynamic and time-like architectures (term derived from the language of Theory of Relativity) that are capable of moving, flexing and reconfiguring themselves through globally networked control mechanisms are emerging. Such buildings maybe “plugged into” the information networks and can be manipulated through remote interaction. Architecture can be published, literally. At this time there is no one theoretical framework available to address such architectural efforts and the paper is aimed at providing a framework under the rubric of “Time-like Architectures”. The paper addresses the unprecedented transformation of the spatial and temporal foundations of architecture by a coming together of two technological developments: global real-time information networks and kinetic, pneumatic tectonics. Envisioned, and, in some cases built, by a group of avant-garde architects, time-like architectures are poised to become a norm in a not too distant future. The paper will identify, define and outline few time-like works. The paper will also outline the historical, theoretical and ethical relationships between post-spatial, post-modern and modern architectures using Charles Jencks’ structuralist classification, Evolutionary Tree.

summary The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building’s Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.
